Differences between protocol and review

We changed the title to reflect the primary outcome and open appendectomy because none of the trials included patients undergoing laparoscopic appendectomy. We included two quasi‐RCTs and performed a sensitivity analysis by excluding the two trials according to the suggestions of the editors and reviewers. None of the included RCTs compared open drain with closed drain (tubes), or early drain removal with late drain removal. Thus, we did not consider these two types of interventions. We added that all patients received similar antibiotic regimens after open appendectomy in the intervention; studies that included participants who did not receive prophylactic antibiotics were excluded, because the use of antibiotic regimens after open appendectomy was found to have a positive effect on clinically relevant outcomes by another Cochrane Review (Andersen 2005). The trials did not report infection at 14 days, therefore the data for 30 days were reported as these data were still considered to be clinically relevant.

We also performed trial sequential analysis (TSA) for the primary outcome intra‐peritoneal abscess. TSA aims to reduce the risk of random error in the setting of repetitive testing of accumulating data, thereby improving the reliability of conclusions.

El uso y la enseñanza del modelo PICO están muy extendidos en el ámbito de la atención sanitaria basada en la evidencia para formular preguntas y estrategias de búsqueda y para caracterizar estudios o metanálisis clínicos. PICO son las siglas en inglés de cuatro posibles componentes de una pregunta de investigación: paciente, población o problema; intervención; comparación; desenlace (outcome).

Trial sequential analysis of drain use versus no drain use for intra‐peritoneal abscess. Analysis was performed with an event rate of 10.7% (Pc) in the control group, a risk ratio reduction of 20%, alpha 5%, beta 20%, and observed diversity 63%. The cumulative Z‐curve did not cross the trial sequential boundaries (inward sloping etched lines). The results showed that the observed diversity‐adjusted required information size was 2,570 participants, corresponding to 20.3% of the total sample size in the included trials. Accordingly, the meta‐analysis did not support or refute an intervention effect as data were too few.

*The basis for the assumed risk is the mean comparison group proportion in the studies. The risk in the intervention group (and its 95% confidence interval) is based on the assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI).
CI: confidence interval; Peto OR: Peto odds ratio; RR: risk ratio

GRADE Working Group grades of evidence
High quality: We are very confident that the true effect lies close to that of the estimate of the effect
Moderate quality: We are moderately confident in the effect estimate: The true effect is likely to be close to the estimate of the effect, but there is a possibility that it is substantially different
Low quality: Our confidence in the effect estimate is limited: The true effect may be substantially different from the estimate of the effect
Very low quality: We have very little confidence in the effect estimate: The true effect is likely to be substantially different from the estimate of effect

a Downgraded two levels for very serious risk of bias.

b Downgraded one level for severe inconsistency (substantial heterogeneity as indicated by the I2 statistic).

c Downgraded one level for serious imprecision. For abscess, morbidity and infection, the confidence interval includes appreciable benefit and harm, and the sample size is small. For mortality, there are few events (8 deaths in total)

d Downgraded one level for serious imprecision (small sample size).
